Starrett Folding Extension Rules
"Don't make'm like they used to", you say? Well, in this case, they actually do. These high quality flat folding rules by renowned toolmaker L. S. Starrett are just like the ones your granddad relied on. They are made from solid maple with rust resistant spring joints. rules are 5/8" wide x 72" long. The deeply embedded graduations and red stud marks are easy to read.
"Deluxe" (SX40F) version reads from left to right on both sides of the rule and includes a brass extension for close-in measurements. "Regular" version (S060F) reads from right to left on one side and left to right on the other, but does not have the brass extension. USA
